I just gave a presentation for the Excel BI virtual group on database theory, and I’m really happy with how it went. I think it’s an undeserved topic quite honestly. So many people in the excel world learn everything ad-hoc and never have a chance to learn some of the fundamentals.
A number of questions came up relating to the engine and how the performance works. If you are interested in more detail on that, I suggest checking out my talk on DAX.
Here are the slides for my talk:
Video is coming soon as well.
